A Framework for Evaluating Schedulability Analysis Tools

open access: yes, 2017
International audienceThere exists a large variety of schedulability analysis tools based on dierent, often incomparable timing models. This variety makes it dicult to choose the best t for analyzing a given real-time system.

Schedulability Analysis of Distributed Multi-core Avionics Systems with UPPAAL [PDF]

open access: yes, 2019
This paper presents an approach for schedulability analysis of Distributed Integrated Modular Avionics (DIMA) systems that consist of spatially distributed ARINC-653 multicore modules connected by a unified Avionics Full-Duplex Switched Ethernet (AFDX ...

A Lattice-Theoretic Formulation for Rate Monotonic Schedulability Analysis

open access: yesMathematics
Fixed-priority schedulability analysis for uniprocessor real-time systems is computationally difficult, and exact Rate Monotonic (RM) analysis is weakly NP-complete.

Formal Modeling and Verification of Embedded Real-Time Systems: An Approach and Practical Tool Based on Constraint Time Petri Nets

open access: yesMathematics
Modeling and verification of the correct behavior of embedded real-time systems with strict timing constraints is a well-known and important problem. Failing to fulfill a deadline in system operation can have severe consequences in the practical case ...

Cache-Aware Timing Analysis of Limited Preemption Scheduling With Fixed Preemption Points in Set-Associative Mapping

open access: yesIEEE Access
In a limited preemption real-time system with a cache architecture, scheduling analysis must not only consider the execution time of tasks and the blocking of lower-priority tasks, but also precisely analyze cache-related preemption delays (CRPD). In set-

Unified overhead-aware schedulability analysis for slot-based task-splitting [PDF]

open access: yes, 2014
Hard real- time multiprocessor scheduling has seen, in recent years, the flourishing of semi-partitioned scheduling algorithms. This category of scheduling schemes combines elements of partitioned and global scheduling for the purposes of achieving ...

Sensitivity Analysis of Strictly Periodic Tasks in Multi-Core Real-Time Systems

open access: yesIEEE Access, 2019
In the design phase of real-time systems, it cannot be expected that the timing attributes of all tasks are completely specified and never changed. The increased computation times or shortened periods in a schedulable system often cause deadlines to be ...

Parameterized Schedulability Analysis on Uniform Multiprocessors

open access: yes, 2010
This paper addresses global Rate-Monotonic (RM) scheduling of implicit-deadline periodic real-time tasks on uniform multiprocessor platforms. In particular, we propose new schedulability conditions that include a set of easily computable task-set ...

Decidable and Undecidable Problems in Schedulability Analysis Using Timed Automata [PDF]

open access: yes, 2003
We study schedulability problems of timed systems with non-uniformly recurring computation tasks. Assume a set of real time tasks whose best and worst execution times, and deadlines are known.
